I've got a polo 6n 1.4 cl 8v. The original steelies were ugly and rusted so when she needed new tyres I got new wheels at the same time. I'm running 15" Fox evo 1's with 195/45R15 tyres. Pretty much got the cheepest tyres halfords were selling, now I know that they'll be the loudest, but I didn't realise that at the time.

The noise is constant in the car and starts to get really annoying above 35mph. I'm also worried that the extra noise is causing unwanted vibrations that is affecting the running gear!

Has anyone had any similar issues or got any tips to tackling the louder road noise

Decent tyres. Until then turn up the radio

Where they balanced before fitting?

Remove exhaust silencers

Instructions unclear, Penis caught in timing belt....

If it really is that bad you couold put in more sound deadening round the wheel arch insides(the inside of the car)

They were balanced, aligned and have got the correct spigot rings on.

They're the only thing that's not stock on all of the running gear.

I have beefed up the stereo so that does help!!

Anyone fitted an upgraded suspension or bushes, and has that had any affect on noise (good or bad)?

Upgraded bushes are normally a stiffer material (polyurethane or nylon) which (over to basic physics) aids sound transfer. In other words it will be noisier.

Could be a stiffer rim too, tyres don't help.

What are pressures set to?

Heavier unsprung mass too perhaps, all contributing factors,

Everything on a car is a compromise, whether it's modified or standard, give and take with components, been fucking around with some rims at work this week actually, same car, same size and offset wheels, same tyres (like swapped onto rims every time) and the car drives differently on each, and feels different. Construction of wheels allows them to flex in different ways, transmit vibrations and other inputs in different ways etc.

This is the tyre that I'm running atm, its not the quietest at 72db but it was the cheapest haha.

Don't know the pressure as when I took it to be aligned they did the pressure for all 4.

It's interesting about the wheels. Never thought about it before, different & unique alloy material combined with wheel design could affect sound and performance as much as the tyre.

Think the next thing to do could be investigate the bushes. Tyres have got too much life in them to get new ones just yet.

£60 for a brand i have never heard of you can get toyo for that. I think u got ripped always best to do some shopping around. New tyres are needed

They were the cheapest they had & came fitted with balancing. I'll probably do a lot more shopping around next time but I guess I'm gona stick with these for time being.

Halfords are generally awful, never understand why people even go there at all, ridiculously priced cheap crap

You could have got a set of kumhos for the same price which are a decent tyre, I've got them on my breadvan and the grip is superb and they're quiet too

It was more out convenience & laziness on part for going with Halfords. Got to say though the tyres grip is great and the noise wasn't an issue at first, just seemed to get loud after they got bedded in a bit. But I'll be shopping around next time I'm in need of tyres, that won't be till these have been worn down a bit more. There's just too much tread left to justify getting new ones now.

If the noise has got progressively worse after fitting wider/heavier wheels then you may want to just check your wheel bearings, as the extra loading may have pushed tired bearings to begin to fail.

The only thing Halfrauds are good for is their professional tools. Reasonable quality, and no questions asked lifetime guarantee replacement.

Swap wheels back and see if it goes away? If there's still a noise there it's obviously something else, that the wheels MAY have caused

I was thinking along the same lines but its hard to tell where the noise is coming from? I'm pretty sure its not diff bearings as gearbox got reconditioned last year & when I noticed the noise I took it back to get the gear box off & it wasn't that. Font near side hub went about 2month ago so I got a secondhand one with a bearing already in and that didn't make any difference.

Before all this happened I had the rear offside bearing replaced (which I'm sure wasn't a VW bearing) now I've read someone had a similar problem with their Passat and the way they solved it was by replacing it with a genuine VW bearing. My thinking is if I need to take it in to garage again it'll be this I'm replacing next??

When I dig the old wheels out I'll give this a try & see what I find out?

i just bought a set of Yokohama S.Drives in that size, 195/45/15 for £55 a corner valved balanced and fitted, so please do shop around next time. - this was at a local place via tyre shopper so no internet price and then finding somewhere to fit them.
